To all whom t may concern.'

" Be it known that I; HENRI RAYMoNo- GUYOT, of 54 Avenue Jean Jaurs, Paris, in the Republic of France, engineer, have invented-al Cooler Ada ted for Use as a Radiator or Condenser, '0 which .the following. is a inll.'A clear. and exact description.

This invention relates to a cooler adapted to be used as a radiator or condenser and designed so as to oiier large radiating surfaces for the purposeof eflicientl'f employin'glx the cooling air or iuid passing therethrough.

The cooler is constituted essentially by: (a) A set of radiation' surfaces or gills (extending for instance in a' horizontal direction) separated from one another by a lurality of vertically-extending combs or istance pieces adapted to engage the ends rom one anther to an--extent approximately equal to l he distance between the gills so as to form cells which give to the assemblage-the aspeet of a honeycomb;

(lf) A' second set of horizontall -extending radiating ills of a length that of .the gil s -of the first set above rc- -r ferrcd to and arranged so that their edges ar located in t e central position of the ce s formedby the first set of radiating gills and the comblike distance pieces;

(c) A plurality of, tubes passing through the two sets of g1llsand serving as conduits for the fluid to be cooled.

By means of this construction .each cell (for-instance) which. comes up a ainst the edge of the small intermediate gil produces ed ies which reduce the speed.- at -which the 'thermore, the friet on between this air and the intermediate gills has also for effect to set up aresistance whichreduces the s eed o f. Aassage ofthe air, and the interme iate gilg themselves. have for eiect to increase the radiating area:x-

In. this l.construction the `assemblage of radiating gills, distance 'p ieces and tubes, forms a 'rigid structure as t e distance pieces fo'lrn .struts vbetween the main radiating slit is to be' noted that the-pa'ssa es for the tubes through the gills are' orme by' pressiii-gout the metal so. that these 4passages are f 'surrounded b yfa metallic. collar engaging ess than air is passed throu h the apparatus. Fur-.

maximum of radiating surface and eilicient employment of the cooling fluid are obtained.

The invention is illustrated by way of example in the annexed drawing wherein Figure 1 is afront elevation of part-'of a cooler wherein the tubes throu h which'passes the Huid to be cooled exten in a direction parallel `with that of the distancepieces 'and' hence are normal t0 the gills. f

Fig. 4 illustrates a portion ofl one ofthe comb-like distance pieces.

Fig. 5 is a. 'vertical section showing a'number of gills.

Fi 6 and 7 are plan views of the large j and of the small gills res actively.

Fig. 13 .is a vertical section on line'13-13 of F1g`. 14, ofa modified -form of constructioii of cooler wherein the tubes for the `section ofl another orizontal sections j may be used in the` passage' ofthe fluid to bel cooled extend in a direction normal to that ofthe distance'- pieces and of thegills. I Fig. 14 is .a section o'n lii1e. 14--14 of- Fig. 13. ig. 15 is a forni of tube adaptedmfor use in theA coistruction of cooler shown in Figs. 13 and 14. As will beseen in Figs. 1 to 7 .of the -drawin s, this construction of cooler comprises a rstset of radiating ills a (eiitendin foi-'instance in a 'horizonte direction) hel horizontal section of another l l together by vertically-extending comb-like pieces'b which engage the ends .of the gills (L and are spaced apart to an extent'approxiv mately equal to the distance betweenthe gills, so'Aas 'to 'form cells which giver-.t0

the assemble e the aspect of a honeycomb.

Between t e gills of the 'firstset arel mounted a second set..of radiating` 'll'so of a length smaller thanthatofthe'gtlls ofy the irstsct and arranged. soas to 'p nt;

their-edge. in the middle of the cells for ed distance pieces.

pressing out the metal to :form around each of the perfor-ations a collar d, the perforations being staggered and adapted for the'arece'ption of the cylindrical tubes e Instead of using cylindrical tubes as-above described, use may be made of' flattened j tubes e as shown in Fig. 8, or of cylindrical [tubes "e2 connected together in group as ,1 -shown' in F ig. 9. "`\Use may also be made of tubes ea constitutedeby two corru ated sheets laid the one on theother as shown in Figs. 1 0 and 11. One of the slieets is furnished With r1bs f crossingI one another and constituting a number of small channels. The two sheets,

n `instead f'being assembled together as above set forth to form al conduit, may be arranged in 'the reverse d1rect1on so as to form' 20 tubular conduits e* (Fig. 12).

Inlthe'moflifed form of cooler illustrated fl Figs. 13 and 14, use is made of flattened tubes .e formed with `an extension as at e the extension vbeing slotted so as to engage gills being slotted and Isaid distance pieces being constituted by notched plates engaging s, id large radiation gills.
